From your hotel, there is no direct bus to reach the Great Wall.
You can walk to reach Dengshikou Station of local subway line 5 to reach Yonghegong Station where you can change to line 2 to reach Jishuitan Station. After that, you can walk to Deshengmen West to take bus 919 to reach Badaling Great Wall directly.
